The Characterizations of the wolf in numerous folktales have ignore
that part of ( ) friendly and gregarious.
A.his natures that are
B.its nature which is
C.his nature which is
D.its nature is
这题答案是B。我不明白何为不选D。正确的句子为The Characterizations of the wolf in numerous
folktales have ignore (that) that part of its nature is friendly and
gregarious.，句中省略小括号中的一个连词that不行吗？如果选D是不对的，请讲解解释一下。谢谢！
